The Yokogawa SAV144-S33 is a 16-channel isolated analog input module designed for Yokogawa ProSafe-RS Safety Instrumented Systems (SIS) and related industrial safety control architectures.
It is used to acquire voltage-based process signals (typically 1–5 V or 1–10 V) from field instruments such as transmitters, pressure sensors, and monitoring devices. The module ensures high-accuracy data acquisition with strong electrical isolation, making it suitable for critical safety applications such as ESD, F&G, and BMS systems.
The “-S33” suffix indicates a specific hardware configuration variant, commonly associated with standard industrial temperature rating and selected installation options within the SAV144 series family.
